Hack my Heat Pump and publish data onto emoncms

Hello,

I have a BRP069A62 connected to a Altherma LT EHVX16S26CB9W (LWT control too). Thanks to your explanation I can connect to the websocket of the altherma, but then how get sensors values ?

I want to monitor all temperatures (outdoor, leaving and returning temp, DHW) and electric power consomption.

Thanks,
Ed
